Before I throw computer out of window and leap myself. (smile), don't know if anyone has any in sight to getting my Eudora to "work" again.

I was in the middle of a large email download (retrieving) when I was "called away" and distracted. While this was going on Windows10 also started it's process. I lost all my email files, and email, and computer wouldn't restart correctly. I was able to go to Windows web site and do on line diagnostics which finished setting up Win10 and put my email folders/email back where supposed to be. I thought all was fine and ready to sing praises for Win10, but now I can't send email. I have check, rechecked, configured, reconfigured smtp settings, etc., and can't think of anything else left to do. No problems retrieving email *(various domain names), but can't send from any domain name. States could not connect, timed out. sigh
